ds has just turned for and had some speech delay in the past - when i am speaking to somebody on the phone (usually my mum) he will demand to speak to them but once handed the phone he will only make 'heavy breathing noises' instead of doing the usual give and take. i have noticed that my neice who is a year younger manages this just fine. is this a skill which they can actually be taught and if so how? my mother suggested quietly prompting in the background but he will not say anything though will start shouting out stuff as soon as he is a meter or so away
